Don't ask for it. want to go to jail.   + +Q: +What card you may suggest me to buy? +A0: +It's for your opinion only but our issues are: +A1: +Speed: +
This +parameter can be computed very easy: +
a) +which movies do you plan to watch: +
- +MPEG1: 320x200@32=256000 +
so +you need only 256*25fps=6.4Mb/sec bandwidth (This format can be played +in real-time on any PC since P-100 + S3Virge) +
- +MPEG4: 640x480@32=1228800 +
you +need videobandwidth 1.2*25fps=30Mb/sec To watch such movie in real-time +you need enough power PC: (Celeron-450+DIMM based video card) +
- +MPEG2 (aka DVD or SDTV): 1024x768@32=3145728 +
you +need videobandwidth 3*30fps=90Mb/sec In extremal cases (if your video card +supports IDCT decoding) this can be played on the same PC as for MPEG4 +
- +HDTV (HighData TeleVision): 2000x2000@32=16000000 +
i.e. +videobandwidth = 16*30fps=480Mb/sec (This means also that you need at least +32Mb of video memory to watch this stream: 16Mb for RGB area and 16Mb for +YUV area) +
b) +Bandwidth of PCI slot is: 33Mhz*32bit=132Mb/sec And PCI2.1 has 66MHz*32bit=265Mb/sec +that is far enough for any movie playback (except HDTV streams which really +require AGP bus). +
c) +What memory type should be installed on video card: +
SIMM +- avoid that +
DIMM +- good if your video card has 128-bit memory access. +
DDR +- is far enough for all types. +
Note: +By DGA comparision - there is no any visible difference between video cards +which have installed the same type of video memory. +
Resume: +If you have enough power CPU (Celeron-450 or K6-2-500) it would be enough +to buy any video card which has at least 8Mb of DIMM or DDR memory. +A2: +Quality: +

If +you are win32 user then probably you have support (from driver and DirectX8 +side) for any feature which was introduced in your chip. +
But +for linux users: +
Currently +I know only several vendors which have more or less advanced support under +Linux: +

Well +- it's very rude observing of video card. Indeed we should pay our attention +for models of video card: +
For +example if MatroxG400(G450) drivers support TV-out then G550 has no such +support. +
Other +sample: Adaptive deinterlacing exists only since Rage128 chip and isn't +present on Mach64+ ones. Same as 3D features are far different from Mach64 +to Radeon2 8500 with trueform possibilities. +

THIS +MATERIAL IS ONLY OUR VISION. +

Q: +If PCI slot is far enough for most types of movies then why S3 Virge +
is +too slow for them? +
A: +Due to its SIMM memory. +  + 5.6. Encoding
